Near Future

A recent development of Advanced Television Systems Committee (ATSC) 3.0 has made over-the-air services of a 4K ultra-high-definition and a simultaneous multiple high-definition soft-landed to reality. However, ATSC 3.0 is in essence designed to be forward compatible, and is hence able to provide better extensible features to enrich the next media era beyond this initial deployment. This paper introduces several selected features of ATSC 3.0 that could play a prominent role in the near future. This investigation encompasses the optional technologies defined in ATSC 3.0 physical-layer which can improve single frequency network integrity, enable additional features in other domains, or further widen the throughput capability. Majorly focused on the extensibility of ATSC 3.0, we also elaborate on possible inter-network cooperation with broadband and cellular systems.

Recent Emergence

The recent emergence of ultra-high-speed and high-definition data and video services has pushed wireless network capacity to its limits. Cellular network capacity is therefore a valuable resource, whereas indoor coverage poses itself as a challenging issue. At the same time, real-world paradigms of multimedia transmission require effective Quality-of-Service (QoS) provisioning as well as power admission. To confront issues like delay-sensitive QoS requirements and traffic provisioning, as well as meet the mobile customer needs, this paper presents a traffic-aware Orthogonal Frequency-Division Multiple-Access (OFDMA) hybrid small-cell deployment for QoS provisioning and an optimal admission control strategy for 4G cellular systems. The traffic awareness in the proposed framework is provided by a utility function, which differentiates the traffic QoS levels with the user's grouping priority indexes, channel conditions, and traffic characteristics. To further enhance the proposed framework, an admission power control algorithm based on an efficient algorithm handover is also proposed.
